What payment terms are accepted?

We accept LC, D/P, T/T, PayPal, Western Union, and small-amount payments.

How does the controller ensure heat dissipation?

The controller uses a TOLL packaged MOSFET welded onto a 2.0mm aluminum substrate, providing excellent thermal conductivity and stable heat dissipation.

What is the warranty or quality guarantee?

We conduct 100% inspection (visual and function) on finished products and have a dedicated QA/QC team of 9 inspectors.
